On "Friends", why was Phoebe fired from her job as a masseuse?

Phoebe was fired from her job as a masseuse after she kissed one of her customers. The customer was Rick Sanoven, an attractive client Phoebe struggled to treat professionally on Friends.

The storyline appears in “The One with the Ballroom Dancing,” the fourth-season episode in which Phoebe keeps trying to suppress her attraction to Rick during his appointments. She eventually admits her feelings, and the two begin kissing while she is supposed to be giving him a massage. Her boss catches them, violating the massage company’s rules against romantic or sexual involvement with clients, and fires Phoebe.

The situation becomes even more awkward when Rick is revealed to be married. Phoebe’s firing is not simply because she had romantic feelings; it follows her crossing a professional boundary by making out with a customer during work. Phoebe later continues working as a massage therapist in other settings, making this one job loss rather than the end of her massage career.
